run.sh currently makes qemu print this as the very first output:
WARNING: Image format was not specified for '_disk_image' and probing guessed raw.
Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
Specify the 'raw' format explicitly to remove the restrictions.
This is scary for people who don't know that this is normal, and
write operations to block 0 being restricted could be confusing
for some operations happening from within serenity too at some point.
So specify the 'raw' format explicitly, like the warning suggests.
Requires using -drive instead of -hda.
From `man qemu-system`:
Instead of -hda, -hdb, -hdc, -hdd, you can use:
qemu-system-x86_64 -drive file=file,index=0,media=disk
So use that, and also pass format=raw.
Attempting to open a non-existent file from the command line should not
fail, it should just open a new text document with that name. Note that
the file is not created until you actually save it.
Oops, these were still using the byte-offset cursor. My goodness is it
unergonomic to index into UTF-8 strings, but Dr. Bugaev says it's good.
There is lots of room for improvement here. Just like the rest of the
tokenizer and parser. We'll have to do a few optimization passes over
them once they mature.
We already convert the input to UTF-8 before starting the tokenizer,
so all this patch had to do was switch the tokenizer to use an Utf8View
for its input (and to emit 32-bit codepoints.)
Until now we would simply apply stylesheets in the order they finished
loading. This patch adds a StyleSheetList object that hangs off of each
Document and contains all the style sheets in document order.
There's still a lot of work to do for a proper cascade, but at least
this makes us consistently wrong every time. :^)
Subclasses that override Element::parse_attribute() must always call to
base class since otherwise we might forget to parse some attributes.
This makes class selectors work on <body> and <img> elements. :^)
This fixes terminal UI resizing in the vim port. The problem was that
vim had "#ifdef TIOCGWINSZ" around the code that figures out the size
of the terminal.
Since all of our ioctl() requests were enum values, this code was not
compiled into vim at all. This patch fixes that. :^)
Now that we flush characters in a single place, we can call the Text's
children_changed() from there instead of having a goofy targeted hack
for <style> elements. :^)
Instead of appending character-at-a-time, we now buffer character
insertions in a StringBuilder, and flush them to the relevant node
whenever we start inserting into a new node (and when parsing ends.)
